Step 6: Mount the retraction tool
• Fasten the lower part of the retraction tool (the ball valve) on the transducer adapter by means
of 4 bolts M 8 x 130 (grade 12.9) using the 6 mm hexagon screw driver. Check the O-ring
sealing, if damaged replace (size 40.87 x 3.53 mm).
• Tighten the M8 bolts with appropriate force using the 6 mm hexagon angled key.
• Make sure that the ball valve is in fully open position.
• Measure the position of the transducer adapter inside the transducer port (depth in the center,
touching the bronze nut) with the ruler.
• Memorize and note this value as "Depth".
INFORMATION!
When properly tightened there should still be some clearance between both plates of the
adapter.
